BUG: the "devs" command returns invalid JSON if no shares have been accepted yet:

Code:

           
    "Difficulty Accepted": -nan,
    "Difficulty Rejected": -nan,

I don't get that when I try:

Code:

"Difficulty Accepted":0.00000000,"Difficulty Rejected":0.00000000

Perhaps you're trying to read them as integers? (They're doubles).

New release: Version 4.7.0, 14th October 2014


Human readable changelog:

- ipv6 support for the API
- Block erupter tube and prisma support
- Support for the avalon nano usb stick
- Support for the --suggest-diff stratum option, currently only supported by ckpools
- Add pool number to addpool response from API
- Make responses to restart and quit from the API valid json
- Change spondoolies sp30 hashrate to valid share based meter
- Add support for a minimum difficulty for slow controllers to not spiral out of control, this will initially make the devices look slow at the pool until vardiff bumps them up properly past the mindiff.
- Change the default queue back to 1 since increasingly devices are on slow controllers and will inevitably increase their queue size to max
- Avalon2 tweaks, show max temperature on command line


Full changelog:

- Implement generic inet_pton for windows
- Fix warnings
- Fix bulk of remaining style in blockerupter.c
- Tidy style in blockerupter.h
- Tidy bulk of style in blockerupter.c
- Fix missing minimum diff setting for blockerupter
- Fix unused variable warnings
- remove unnecessary sleep; fix potenital div by 0 errs; use min_diff in driver
definition
- Fix coding style
- Make the sp30 hashrate meter based on valid share generation
- Change default max queue back to 1 in line with speed of most current asic
controllers
- Change diff limits to values suitable for sp30
- Add pool number to response from addpool to the API
- Make the restart and quit API commands valid json responses
- Fix number of nos
- Add option to set clock ('--bet-clk X' actual clock is (X+1)*10 )
- compatible with X24 board
- Fix error when using v6 without mask in api-allow
- Support ipv6 multicast
- Set min_diff to 1
- Allow arbitrary clamping of lower device diffs for slow controllers by driver
- Don't set default fan to max on hashratio
- The 2nd read never gets anything on ava2 so remove it entirely and just return
an error if we are out of sync
- Implement support for mining.suggest_difficulty
- Fix client ip address output
- Free addrinfo garbage
- Remove the brackets when using v6 pool address
- Add ipv6 support for api listen
- Avalon Nano: Add support Avalon Nano usb miner
- fix bug in setdiff
- limit minimum diff to 64
- Add BlockErupter Driver
- Avalon2: display currect max temperature on statline
- Remove unused variable

Hello,

Support the Cgminer in the stock version also the Technobit:

240 GHs HEX8A1 Coincraft A1 miner?

sudo ./autogen.sh --enable-hexminera --enable-hexminerc --enable-hexminerb --enable-hexmineru --enable-hexminer8

or only with the HEX patch?

THX

[ManeBjorn]

Do we use the zadig drivers for the Avalon Nanos or is there a different driver?
These things are buggy that is for sure.

- Support for the avalon nano usb stick

All cgminer USB on windows uses zadig - same driver config for everything.

Crazy unicode character showing up in cgminer "stats()" response: https://github.com/hashware/node-cgminer-api/issues/10#issuecomment-59324280

Maybe its a Antminer thing, but cgminer shouldn't let invalid JSON be returned.

[tjwebb]

Perhaps you're trying to read them as integers? (They're doubles).

0.0000 is not valid JSON at all, for anything. It should just read 0.0.

My workaround is here, so you can see: https://github.com/hashware/node-cgminer-api/blob/master/lib/client.js#L105. I have to manually replace "nan" with 0, otherwise JSON.parse() fails.

[spiceminer15]

anyone have any idea with w_allow low level detected  errors specifically with btcgarden am-v1

[spiceminer15]

anything special I need to do to compile cgminer to work with btcgarden asics?

[-ck]

anything special I need to do to compile cgminer to work with btcgarden asics?

We don't have any specific code for that hardware so I'm guessing only an unofficial cgminer fork supports them so you'll have to seek help from whoever maintains that fork.

[spiceminer15]

damn. thanks for the info

Anyone have a guide to cross compiling CGminer?

Here is my environment:

Ubuntu 14.04 LTS 64-bit on XenServer w/ 8GB RAM and 8-cores.

I have installed all the multi arch tools for CubieTruck  (ArmL7) and can build the kernel and other tools.

Where I am having problems:

1. Configure says I don't have curses library or libudev installed.

2. When I try to compile, I get errors about curl functions.

Cross compilation is not for the faint of heart. One thing to be wary of is most cubie distributions are older glibcs than what ubuntu has probably installed so that even if you get it to compile you will not be able to run the binary on your cubie.

To get yours compiling, provided you don't care about the text interface, or getwork/gbt/solo support, use git master and you can just add "--disable-libcurl --disable-udev"

The CubieTruck build I am working with is a full version of Debian Weezie and CGminer will build on it without any problems. What I am looking for is how I get the dependencies to show up in the cross environment.

A little addition to my previous note on CGminer 4.7.0 getting into Debian Sid. It got built for all architectures.

If you are running Jessie you can manually pull the package down from your favorite mirror and install it with the "dpkg -i " command.

[Ntrain2k]

Any tips for getting the correct speed out of CGMiner for the new/old R-boxes?

I've tried several flavors, including the one from rockminer and can't get anywhere near the speed I get with bfgminer which runs the new r-boxes slow to begin with.
